Processing graphs...

...how the heck?!

I have do user inputted curves. They are visually similar? I need to compare them for their similarity?

Can anyone link me to some tutorial/methodologies on how to do this in OOp?

My only idea was to extract a formula for both curves an then play a bit with mathematics?

Anyone can point me to some links please?

Thanks!

He is either an idiot or a troll willing to know about the FFT. Anyways the result will be somewhat HIBT?^metatroll similar.
